>Originator: SanTropez &
>Release: All versions of FreeBSD from 3.1-release to 4.0-current
>Organization:
Rensselaer Polytechnic Institute
>Environment:
Bug is for anyone using 'lpc' (part of lpr) in any recent version
of FreeBSD, including the latest snapshot of current.
>Description:
Do the following commands:
lpc stop somequeue
lpc status somequeue
lpc start somequeue
lpc status somequeue
and you will see that even though the third command CLAIMS that
it has enabled printing, it has in fact done nothing. You have
to:
lpc up somequeue
to get printing enabled again.
>How-To-Repeat:
See the description.
>Fix:
The following is basically a repeat of the patch included in
bin/13549 and reinterated (by someone else) in bin/14975. Note
the version in bin/14975 is somewhat "backwards", so it's easy
to glance at that & the original code and think that the patch
has already been applied. This patch had not been applied as
of Dec 20th or so.
